The panel that will study and make recommendations on regulating marijuana in Massachusetts — the first piece of a growing regulatory structure — is on track to be finalized by the end of the week when the governor names the final five members.

Treasurer Deborah Goldberg and Attorney General Maura Healey both made their required five appointments to the Cannabis Advisory Board by the end of Tuesday, the deadline set by the law Gov. Charlie Baker signed on Friday.

Baker also must make five appointments to the board and his office said Wednesday his appointments will be announced by the end of the week.

Goldberg named her five on Friday: Norton Arbeláez, founder of Colorado's Medical Marijuana Industry Group; former Brookline director of public health and human services Dr. Alan Balsam; Sage Naturals president and CEO Michael Dundas; Jaime Lewis, founder of Mountain Medicine; and co-chair of the Northeast Cannabis Coalition Shanel Lindsay.

Healey made her picks public on Tuesday: former secretary of the Executive Office of Public Safety and former sheriff of Suffolk County Andrea Cabral; Horace Small, executive director of the Union of Minority Neighborhoods; Ray Berry, founder of White Lion Brewing Company in Springfield; Tessa Murphy-Romboletti, director of the Greater Holyoke Chamber Centennial Foundation's entrepreneurship program; and Dr. Sharon Levy, director of adolescent substance abuse at Boston Children's Hospital.

The Cannabis Advisory Board will also include Baker's five picks and 10 other members, most of whom are specifically named by title in the law. They include the colonel of the Massachusetts State Police or a designee, the secretary of housing and economic development or a designee, the revenue, public health and agricultural resources commissioners, and the heads of the local ACLU chapter and the Massachusetts Municipal Association.

Nichole Snow, president and executive director of the Massachusetts Patient Advocacy Alliance, will also serve on the board and named Michael Latulippe, a medical marijuana patient who works with the alliance, to the board on Tuesday.

By Sept. 1 the three constitutional officers — Baker, Healey and Goldberg — must appoint the five-person Cannabis Control Commission, which will manage the licensing and oversight of the budding industry.

Baker must appoint someone with a background in public health, mental health, substance use, or toxicology; Goldberg must tap someone who has a background in corporate management, finance or securities; and Healey must appoint someone with a background in public safety. Then the three constitutional officers must agree on the final two appointments, which must be people with experience working in or with regulated industries. Healey on Tuesday asked that anyone interested in the position submit an application by Aug. 15.

Goldberg will appoint the chair of the commission, though the ballot law approved last year had given the treasurer total control of the commission.

Once the CCC is up and running, it will have to "promulgate regulations, guidelines and protocols necessary for the issuance of (marijuana) licenses" no later than March 15, 2018 and begin accepting applications by April 1, 2018, according to the law.
